Thank goodness for the Intuit/TurboTax message boards. This is the solution and thank you so much for posting it.
The following steps (which were recommended by someone else in another post) seem to have solved this issue for me: (a) Restart the computer; (b) Start Turbotax and, when it asks for a keychain password, enter your computer screensaver or login password and click "always allow". Good luck.
